three.js四边形线框

嗨，社区！
这里有一个解决方案，适用于那些通常是扭曲平面的几何图形。nhttps://jsfiddle.net/prisoner849/sgaywqf3/show35778×544 18.1kb

谢谢！这个环形的正是我需要的！
编辑：这真是太棒了。
我在几何体上的计数增加了，在线框上的计数减少了，这是一个低计数、平滑的四元线框。
看起来就像NURBS。nPerfecto

为什么js fiddle不能在手机上正常工作？？

看看这个着色器的工作原理有多棒。
我刚换了一个茶壶的圆环。
不需要任何额外的调整就可以跟踪不同部分的轮廓。nquad_teapot1038×646 142 KBn@GlifTek看起来不错，我通常用它来做这些事情，可视化UV坐标。
我如何为缓冲区几何体做到这一点，我不想删除中间线，我只想让它不可见，这样我的几何体仍然具有相同的结构，即线框1152×648 1.12 KB，这篇文章有一个JSFIDLE，带有GUI选项“四边线框”。或者你的意思不同？
